A simplified chemical reaction mechanism for surrogate fuel of aviation kerosene

Abstract

n-Decane was chosen as a one-component surrogate fuel to investigate the combustion performance of Rocket Propellant-3(RP-3) aviation kerosene. Sensitivity analysis and the reaction-path analysis method were used to simplify the detailed reaction mechanism of n-decane, and a simplified mechanism including 36 species and 62 elementary reaction steps was obtained. Moreover, 38-step elementary reaction investigated in the reference was simulated in the paper. Numerical simulation method was conducted for both the 62-step and the 38-step reaction mechanisms using pre-evaporation combustion models. Simultaneously Bunsen burner for the combustion of premixed, pre-evaporated RP-3 aviation kerosene was designed to verify the simplified mechanism, and the temperature and gas component concentrations in the axial and radial directions at different heights were measured. The experimental results revealed that the reaction temperature and the CO₂ concentration increased first and then decreased across the axial positions, but on the contrary for the O₂ concentration. The temperature and the O₂ concentration distributions of experimental results are in good agreement with that of numerical simulation results for the 62-step simplified reactions, and the CO₂ concentration distribution is in general agreement with the numerical data. But the 38-step simplified reactions can only predict the change trend for the important parameters which are mentioned above. Through the contrastive analysis for these two kinds of simplified reactions, the 62-step reactions can more accurately simulate the combustion characteristics of RP-3 kerosene. And n-decane can be used as a one-component surrogate fuel for RP-3 aviation kerosene.
